Dipteran flies are important ectoparasites of cattle that causes economic losses by virtue of their ability to cause annoyance, blood loss, and act as a vector of widespread diseases. The abundance of dipteran flies affecting the dairy population is poorly documented in India and the present study was planned to investigate the diversity and seasonal abundance of dipteran flies in and around Bhubaneswar. Dipteran flies were collected from cattle sheds and habitations for one year (August 2017 to July 2018) covering four seasons. Higher recovery of flies was documented for Musca fly (21.51%) followed by mosquitoes. Amongst different mosquitoes, Culex spp. was the most common (18.11%) followed by Aedes spp. (11.58%), and Anopheles spp. (8.82%). Stomoxys fly, Tabanus fly, Chrysops fly, Sarcophaga fly, Hippobosca fly, and Coproica fly showed a relative abundance of 10.29%, 9.93%, 6.8%, 6.07%, 4.5%, and 2.39% respectively. There was significant variation (p < 0.01) in the seasonal abundance of flies. The highest relative abundance of flies was recorded in June whereas the least relative abundance was from November to January. The correlation analysis of the monthly fly population with climatic factors showed a highly significant correlation (p < 0.01) of the fly population with average temperature (r = 0.840), average relative humidity (r = 0.808), and rainfall (r = 0.796). The present communication reports abundance of different biting and non biting flies around cattle habitations and the insect activity were dependant on climatic parameters.
